HA BES - BAS DNS Pool?

I can't get a straight answer out of rim. I have BES running in HA config (prim/standby). Only 1 BAS can be active at 1 time with this configuration. Connection is rejected to the standby BAS even if the services are running.

Monitoring service requires a BAS address. Monitoring is essentially useless if the BAS is switched standby instance as the hostname is different.

What's the best way to deal with the issue? Set up a DNS record pointing to both servers?
